Sticking close to their purported iPhone 5 digitizer, showing a larger display and a thinner bezel, iDealsChina has now posted several “mold engineering drawings” for the fifth-generation iPhone.

We just got what appears to be mold engineering drawings for iPhone 5. These would be used by case designers to create plastic, TPU, aluminum, silicone and leather cases. A while back we hear rumors that iPhone 5 would have a curved back but these images show iPhone 5 with the same form factor as iPhone 4 but with an edge to edge screen.

Interestingly enough, these images depict an iPhone 4-like design – with the same wrap-around antenna – but with a larger display and a thinner bezel. This larger display and thinner bezel goes hand in hand with reports from Digitimes and the Wall Street Journal, respectively.

The images (above and after after the break) do not show much else but the interesting part from their description is that these images are said to be case mold drawings. The last case mold drawings we saw were for the iPad 2 and they seem to have been almost, if not, 100% accurate.
